Yes, and I think some shoe boxes still have those things left in the boxes from being in a warehouse or whatever. TBH unless you live somewhere incredibly humid there's nothing the shoes can't handle and even in humid environment a bit of moisture in the air should have no ill affect.
If you are concerned take them out every so often and give them a wipe with a soft cloth. I've had shoes that I've not worn for months and months and never had any damp or mildew issues
